Error saving List<Enum> to config

I have the following enum:

Code:

public enum Actions { CRAFT, USE, PLACE, BREAK, PICKUP }

When I do:

Code:

//rule.getActions() returns List<Actions>
getConfig().set( path , rule.getActions() );

I get this in my config:

Code:

    actions:
    - !!com.github.mineGeek.LevelRestrictions.Managers.Rule$Actions 'PLACE'

This causes reloading the config to barf all over the console.
Tried looping through to create a string, but config wraps in -> '
Using the exact same code but on a List<Integer> works as expected (which is to say it works!)

Can't seem to find the solution. Thanks in advance for any insight, help or solutions!
